Environment-friendly high-strength carbon brick for blast furnace and preparation method thereof
The invention discloses an environment-friendly high-strength carbon brick for a blast furnace and a preparation method of the environment-friendly high-strength carbon brick, and relates to the field of carbon bricks for blast furnaces, the environment-friendly high-strength carbon brick comprises the following raw materials in parts by weight: 5-20 parts of mixed dust collecting powder, 4-8 parts of silicon carbide powder, 8-12 parts of silicon powder, 3-6 parts of superfine crystalline flake graphite and 1-2 parts of silica powder which are used as matrixes, and 50-65 parts of roasted fragments which are used as aggregates, thermosetting phenolic resin accounting for 15-25 parts of the sum of the matrix and the aggregate is added as a binding agent; the matrix and the aggregate are placed in an Erizon powerful mixer. The mixed dust collection powder is obtained by mixing dust collected by a dust remover in a batching process, a crushing process and a machining process in a triple-spiral mixer; the roasting fragments are obtained by crushing and screening waste carbon bricks after high-temperature roasting or recycled old carbon bricks. Most of the used raw materials are waste recycled materials, the preparation process is simple, the cost is low, the green and environment-friendly effects are achieved, and the prepared product is high in strength, high in heat conductivity and excellent in molten iron corrosion resistance.
本发明公开了一种高炉用环保型高强度炭砖及其制备方法，涉及高炉用炭砖领域，所述其原料包括以下重量份的份数：5~20份的混合收尘粉、4~8份的碳化硅粉、8~12份的硅粉、3~6份的超细鳞片石墨的和1~2份的硅微粉为基质，以50~65份的焙烧碎为骨料，外加所述基质和所述骨料之和的15~25份的热固性酚醛树脂为结合剂；将基质和骨料置于爱立许强力混合机中。所述混合收尘粉是将由除尘器在配料过程、破碎过程以及机加工过程中收集的粉尘按置于三螺旋混合器中混合得到的；所述焙烧碎为高温焙烧后的废炭砖或回收旧炭砖经破碎、筛分后得到的。本发明所用原料大部分为废旧回收料，制备工艺简单、成本低而且绿色环保，所制制品强度高、热导率高和抗铁水侵蚀性能优异。
